Non-isothermal desorption of droplets of complex compositions

Abstract

This paper presents the process of non-stationary evaporation of aqueous solutions of LiBr-H₂O, CaCl₂-H₂O, NaCl-H₂O droplets on a horizontal heating surface. The following typical stages of heat and mass transfer depending on wall temperature have been considered: evaporation below boiling temperature and nucleate boiling. The significant decrease in desorption intensity with a rise of initial mass concentration of salt has been observed. Formation of a surface crystallization front at evaporation of a droplet has been detected. We have developed the experimental method for direct measurements of the mass of evaporating droplet.
